Nikola Tesla's Colorado Springs Notes

Colorado Springs Laboratory (1899-1900)


"Tesla dedicated most part of his research to develop the right design of a wireless power transmission system to be able to energize the whole planet without wires and to send signals or messages instantly and non-transferable.

Excerpt from "On electricity" - Electrical Review - Jan. 27, 1897:

"In fact, progress in this field has given me fresh hope that I shall see the fulfillment of one of my fondest dreams; namely, the transmission of power from station to station without the employment of any connecting wires."

Tesla's went to Colorado Springs in mid-May 1899 with the intent to research:

  1. Transmitters of great power.
  2. Individualization and isolating the energy transmission means.
  3. Conditions of propagation of currents through the earth and the atmosphere.

In early 1902 Tesla sent a letter to J.P.Morgan to explain his research in which he evisaged the following distinct steps to be made:

  1. The transmission of minute amounts of energy and the production of feeble effects, barely perceptible by sensitive devices;
  2. The transmission of notable amounts of energy dispensing with the necessity of sensitive devices and enabling the positive operation of any kind of apparatus requiring a small amount of power;
  3. The transmission of power in amounts of industrial significance. With the completion of my present undertaking the first step will be made.

Tesla spent more than half his time researching transmitters. Tesla spent less than a quarter of his time researching delicate receivers and about a tenth of his time measuring the capacity of the vertical antenna. Also, Tesla spent a tenth of his time researching miscellaneous subjects.

J. R. Wait's comment on Tesla activity: "From an historical standpoint, it is significant that the genius Nikola Tesla envisaged a world wide communication system using a huge spark gap transmitter located in Colorado Springs in 1899. A few years later he built a large facility in Long Island that he hoped would transmit signals to the Cornish coast of England. In addition, he proposed to use a modified version of the system to distribute power to all points of the globe". The authors note that no alterations have been made to the original which still contains certain minor errors; calculation errors which influence conclusions are noted. The authors also note the end of the book contains commentaries on the Diary with explanatory notes."
